On Saturday, we were thrilled to host Yuen Ting’s demonstration of the air cannon she assembled from her most recent rewards-card prize score: Klutz Maker Lab’s Air Blast Cannon, one of a series of STEM-oriented kits. The air cannon set uses syringes to provide the oomph needed to propel familiar rubber-headed foam darts at the press of a charmingly large cardboard switch. Well done, Yuen Ting!
